I'm putting together the fuel system for my new sfwd car. I could go with 10an to the pump, then 8an up to the rail and 6an back, but because of some stuff I already have, it's gonna be cheaper to run all 10an and then 6an return. Is there any reason that being a little larger than I need will be bad?
thanks,
Jared

 

only things that I can think of that would be bad....

1 Fittings more expensive
2 burst psi might be alittle lower

 

That's about all I could come up with too. I guess I'm gonna go with the 10an all the way because I have all kinds of 10 an stuff already, save me a little money in the long run.
thanks,
Jared

 

i ran 10an out of my tank, to the fuel filter, to the pump, and to the fuel rails. fuel pressure gauge at the end of the fuel rail and 6an return to the tank. worked perfectly.

 

Only bad thing I can think of is the weight of the fuel in a large line is more. It
needs to work ageinst acceleration, the pump will need to work harder.
